I also quite agree with what you said because a team as big as Real Madrid basically already has some of the best players so it would look quite good to be able to get Mbappe to fill their squad next season. So Real Madrid can have the option of saving money by not sacrificing the team's performance next season because I am also quite sure that Real Madrid will be much better than the previous season in terms of competition and their performance unless there are many mistakes that can prevent them from performing well next season.
If Haaland and Mbappe join forces and play together in Madrid then it can be certain that Madrid has a very perfect attacking line and it will be scary for their opponents, this season Madrid has a very dangerous attack when they only rely on Vinicius, Rodrygo and also Bellingham, so that currently they are able to make Madrid win the La Liga trophy and also the Champions League,So we can imagine how dangerous Madrid's attack will be when next season Mbappe will also join and of course we will see how easily Madrid attacking attackers destroy the defense of each of their rivals in a match.
Speculation about Haalaand joining Madrid is of course only an uncertain issue, but I think it is possible to happen if indeed Perez ambition to build Los Galatics to become the greatest team that exists later, the financial ability possessed by Madrid is of course undeniable if the possibility can be realized, and when it is realized, it is likely that Madrid will be able to dominate not only in La Liga But in other competitions, it is likely that they will be very easy to win.
